Verses 1-3:
"Arad" was the name of a Canaanite king who lived in the Negev (the south, see Nu 13:17). It was also the name of the place where he lived, Jos 12:14; Jg 1:16. Scripture indicates it lay in the southernmost part of the territory assigned to Judah. Eusebius locates it about twenty Roman miles south of Hebron. Modern geographers place it as Tel-Arad.
"Spies," atharim, "places or districts," so translated in Ezr 5:15, 6:3, 5, 7; Da 2:35. This term implies that a specific place is meant; note that spies brought a report to the king. It appears that this place was so named because it was the route the spies took when sent by Moses to scout the Land.
Arad learned that Israel proposed to travel this route. He launched a surprise, unprovoked attack, and took a number of them prisoner. This attack was not a Divine judgment for disobedience.
Israel vowed to destroy Arad’s cities if Jehovah would give victory in battle. God heard their prayer, and delivered the Canaanites into their hand. Israel kept their vow, and utterly destroyed the cities of Arad.
"Hormah," meaning "a devoted place," one set apart for destruction. The site is today Tell es-Sheriah, about midway between Gaza and Beersheba. This name denotes the site of Israel’s defeat by the Amalekites, Nu 14:45; De 1:44. But in the encounter with Arad, Israel was victorious!
